OPERATION ON BIOFUEL
All Grant Vortex condensing boilers manufactured since May 2011 are suitable
for operation on both standard Kerosene (Class C2 to EN 590) and also bio-
kerosene - up to a 30% blend (B30K).
All burner settings and nozzle sizes (as detailed in Section 2.2 of these
instructions) are correct for both standard kerosene and bio-kerosene (B30K).
In order to operate this boiler on bio-kerosene, it will be necessary to take the
following actions:
• Use a bio-kerosene (B30K) compatible fl exible oil line in place of the oil
line supplied with the boiler.
• Have the oil storage tank and oil supply line (including all pipework,
sight gauges, fi lters, isolating valves, fi re valves, de-aeration devices, etc.)
checked for their compatibility with bio-kerosene (B30K).
Where necessary, some or all of these items may have to be replaced
with a bio-kerosene compatible alternative.
• Check the suitability of the fl ue system with Grant Ireland.
• Use only bio-kerosene (B30K) that conforms to OPS24.
IMPORTANT:
Under no circumstances, should the boiler be used with bio-
kerosene without the above actions being taken fi rst.
